| − | This product is an E-paper device adopting the image display technology of Microencapsulated Electrophoretic Display, MED. The initial approach is to create tiny spheres, in which the charged color pigments are suspending in the transparent oil and would move depending on the electronic charge. The E-paper screen display patterns by reflecting the ambient light, so it has no background light requirement. ('''Note that the e-Paper cannot support updating directly under sunlight''')

| | | | |
| − | Note: Different from the traditional SPI protocol, the data line from the slave to the master is hidden since the device only has display requirement.

| + | |heading = Working with Sunrise X3 Pi |
| − | * DC is data/command control pin, when DC = 0, write command, when DC = 1, write data.
| + | |content = User guides for the development demo based on Python}} |
| − | * SCLK is the SPI communication clock.
| |
| − | * SDIN is the data line from the master to the slave in SPI communication.
| |
| − | SPI communication has data transfer timing, which is combined by CPHA and CPOL.
| |
| − | # CPOL determines the level of the serial synchronous clock at idle state. When CPOL = 0, the level is Low. However, CPOL has little effect to the transmission. | |
| − | # CPHA determines whether data is collected at the first clock edge or at the second clock edge of serial synchronous clock; when CPHL = 0, data is collected at the first clock edge.
| |
| − | * There are 4 SPI communication modes. SPI0 is commonly used, in which CPHL = 0, CPOL = 0.
| |
| − | As you can see from the figure above, data transmission starts at the first falling edge of SCLK, and 8 bits of data are transferred in one clock cycle. In here, SPI0 is in used, and data is transferred by bits, MSB first.

| − | === Set the frame memory (SetFrameMemory) ===
| |
| − | SetFrameMemory is used to write image data to the memory.
| |
| − | * Process:
| |
| − | :: Set the area size (see the function SetMemoryArea) -> set the start point (see the function SetMemoryPointer) -> send the command ''Write RAM'' -> start image data transfer.
| |
| − | * The module has two memory areas. Once DisplayFrame is invoked, the following action of SetFrameMemory will set the other memory area, e.g. to set all the two memory areas, the process is: SetFrameMemory -> DisplayFrame -> SetFrameMemory -> DisplayFrame, i.e. set and update twice.
| |
| − | * The data from SPI interface is first saved into the memory and then updated if the module received the update command.
| |
| − | * About the image to be sent: 1 byte = 8 pixels, doesn’t support Gray scale (Can only display black and white). A bit set stands for a white pixel, otherwise a bit reset stands for a black pixel.

| |
| − | 0x00：8 pixels ■■■■■■■■
| |
| − | 0xFF：8 pixels □□□□□□□□
| |
| − | 0x66：8 pixels ■□□■■□□■
